Abstract

The invention provides a continuous dredging device for river regulation, and relates to the technical field of river regulation. The dredging device is arranged on a dredging ship and sequentially comprises a cutter suction part, a screening part and a collecting part according to the passing sequence of silt. According to the dredging device, fine mud is pumped into one geotextile tube bag through a first mud pump, when the geotextile tube bag is about to be full, a three-phase valve is adjusted to guide the mud into another geotextile tube bag, and when water separated out of the first geotextile tube bag is about to flow out, a delivery ship is arranged to be connected with the dredging ship, and a lifting permeable plate is lifted; and the first geotextile tube bag slides to the delivery ship along the inclined plane of the bottom of a drainage tank under the action of gravity, the delivery ship recycles and delivers the geotextile tube bag to a factory for direct reutilization, meanwhile, an empty geotextile tube bag is placed in the drainage tank, when the geotextile tube bag on the other side is about to be full, the process is repeated, continuous dredging work can be achieved, the dredging device is not limited by a storage yard and a pipeline transportation system any more, the degree of freedom is higher, and the working efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of river channel regulation, in particular to a continuous dredging device for river channel regulation. Background technique [0002] The dredging and decontamination of river courses and lakes is a major problem related to urban and rural environmental protection and the health of residents. At present, traditional dredging works mainly include dry water operation and water-carrying operation. [0003] Dry water operation refers to setting up temporary cofferdams, draining the water in rivers or lakes, and using excavators to dig out the silt. The dredging is thorough, but it requires a lot of manpower and material resources. Rain and snow will also affect the construction, which is inefficient . Therefore, more advanced water-carrying operations are often used for dredging at present. [0004] The operation with water generally refers to installing the dredging device on the ship, and the dredging ship...
